Chemical-looping combustion

Coke formation is an obstacle that would limit the efficiency of the total CO2 separation. Therefore, it is important to minimize its formation by selecting an appropriate oxygen carrier and adjusting the reaction conditions. In this study, it was observed that the measured amount of carbon deposited on the oxygen carriers after the 10th reduction step is negligibly small. Ryd n et al. ako observed no carbon formation on La cSri e03 5 [68]. [Pg.58]

Interestingly, a strong dependency of the catalytic properties on the CH4 pressure was observed for these materials. In particular, higher stability and no [Pg.58]

A modified gas turbine cycle, a H2-fueled chemical-looping combustion, has been proposed in Japan. The oxidizer air or oxygen is replaced by a solid metal oxide, e.g., NiO. An increase in the efficiency up to 66.8 % is predicted compared with 61.6 % as the best figure for H2/O2 cycles [23]. [Pg.186]
